Eaton HGLL 12C Grounding Bushing - NEC/CEC Compliance
Part Number: HGLL 12C
Quick Summary
Grounding Bushing HGLL 12C provides a robust grounding connection for rigid/IMC conduit installations in industrial panels and outdoor enclosures. Engineers frequently struggle with securing a low-resistance bond that endures vibration, temperature, and installation tolerances without compromising code compliance. This part is NEC/CEC compliant and UL-listed for US and Canada, with a 150°C rating and a copper lug capable of accepting #3/0-6 AWG conductors. The malleable-iron body and threaded design simplify installation in tight spaces while delivering long-term reliability. For procurement and field teams, HGLL 12C combines high-performance grounding with supplier-ready documentation, supporting project timelines and reducing rework in ordinary/non-hazardous locations. This makes it a practical choice for rugged industrial wiring projects needing durable, code-certified grounding connections.

FAQs
HGLL 12C is designed for threaded connections to rigid/IMC conduit and uses a copper lug sized for #3/0-6 AWG conductors. For best results, align the bushing with the conduit axis, tighten to the manufacturer’s torque specification, and verify a snug, low-resistance bond between lug and conductor. Refer to Eaton’s HGLL 12C specification sheet for exact torque values and tightening sequence.
HGLL 12C features a copper lug capable of #3/0-6 AWG conductors, a malleable iron threaded body, a 6 inch trade size, and a 150°C temperature rating. It is compatible with rigid/IMC conduit and is designed for use in Ordinary/Non-Hazardous locations, with NEC/CEC standards and UL certifications applicable for US and Canada.
No. The HGLL 12C is specified for Ordinary/Non-Hazardous Locations. For hazardous environments, you should select grounding bushings rated for specific hazardous classifications and confirm with the applicable standards and certifications before deployment.
HGLL 12C carries NEC/CEC standards and UL certifications for the United States and Canada, as shown in Eaton’s certification references. See the UL certification pages for US and Canada and the Eaton specification sheet for confirmation of compliance, installation guidelines, and verification of listing details.
The device offers a durable malleable-iron body, threaded connection, and copper lug that supports efficient, high-current bonding with minimal parts. This reduces installation time, lowers inventory complexity, improves reliability in high-temperature environments, and supports regulatory compliance—leading to lower maintenance costs and faster project completion.
